Hello,
I write this message just to say, that in my experience the new feature "Simulate Air Absorption" for the direct signals is a subtle but in the meantime a very useful, audible improvement. More depth in the stereo soundstage (more natural sound!) but it is also very easy to make little changes in the sound of especially solostrings by changing the direction a little (I was working on a piano quintet). For me it means being at work on my music with even more joy. Also the possibility to switch that feature on or off for every instrument independently is very useful. I used that possibility in a piece for choir and orchestra. It is a recording of a real choir combined with a VSL symphony orchestra. To keep the words understandable as much as possible, I switched off the feature for the choir. So, a thankful user!
